Visual rehabilitation with mini scleral contact lenses in scarred corneas.

PURPOSE: To present a case series of patients with corneal scars who were successfully fitted with mini scleral contact lenses (mSCL). METHODS: Case series study. RESULTS: Six eyes of six patients with corneal scars were fitted with mSCLs. All scars were situated in the visual axis within the scotopic pupillary zone. The sizes of the scars varied, with the smallest being confined to a central corneal area (case 5) and the largest covering the entire visual axis (case 2). In addition to compromising corneal transparency, these scars also induced significant corneal irregularities, especially in cases 1, 3, and 4. The average corrected distance visual acuity (CDVA) with spectacles was 20/80, with a range of 20/200 to 20/40. With the use of mSCLs, CDVA improved to an average of 20/25, ranging from 20/40 to 20/16. The mean visual acuity improvement observed was five optotype lines, with a range of 3 to 7 lines. CONCLUSION: Corneas with scars often exhibit increased higher-order aberrations (HOA), and affected patients not only experience reduced vision but also suffer from seriously reduced optical quality and optical phenomena such as photophobia. Utilizing mSCLs in such individuals can significantly enhance visual acuity and improve optical side effects resulting from corneal opacity and irregularity.

Implementation of delayed intervention in open approach rhinoplasty for patients with supratip scarring.

INTRODUCTION: The columellar incision and dissection which were integral steps in open rhinoplasty play a crucial role in achieving optimal results. However, scarring in the supratip region may pose challenges to skin circulation, potentially leading to complications such as flap loss. OBJECTIVES: This study aims to establish the safety and efficacy of the open rhinoplasty technique as a viable alternative for patients with substantial scars in the supratip region typically addressed using the closed rhinoplasty technique. PATIENTS AND METHODS: Patients with scars on the tip or supratip region were operated clinic between February 2010 and March 2023. To mitigate the risk of tip necrosis, a meticulous two-step delay approach was employed. In the initial outpatient procedure, performed under local anesthesia, we opted for a columellar incision. Subsequently, the columellar arteries were identified and cauterized to facilitate the delay procedure. Following a ten-day interval, all patients underwent standard open rhinoplasty. RESULTS: The columellar artery delay procedure proved instrumental in executing successful open rhinoplasty without compromising skin circulation between the scarred supratip and columellar incision line. CONCLUSION: Our findings suggest that the columellar delay procedure effectively prevents flap loss in open rhinoplasty patients with scars in the supratip and columellar regions. This brief outpatient intervention, lasting approximately ten minutes, provides a reliable method for adopting the open approach in primary rhinoplasty cases, irrespective of prior scarring. LEVEL OF EVIDENCE: Level IV, therapeutic study.
